RESEARCH

My main PhD project focuses on the study of inclusive semi-leptonic decays of $B_{(s)}$ mesons through Lattice QCD simulations.

Precise theoretical predictions for particle physics models are key ingredients for pushing forward our understanding of Nature. While our current mathematical formulation - the Standard Model - has proven to be extremely successful, experiments have recently started to show deviations from it in sectors involving particles containing heavy quarks, as for example $B$ mesons.
In this project we propose to address the non-perturbative calculation of the decay rate of the inclusive semi-leptonic $B_{(s)}$ (and $D_{(s)}$) mesons decay in the Standard Model using theoretical and numerical techniques available from lattice QCD. In particular, the project aims to predict the ratio between the decay rate of the mesons and some Cabibbo-Kobayashi-Maskawa matrix elements, specifically $|V_{cb}|$ and $|V_{ub}|$.
These results will represent the first fully non-perturbative theoretical predictions for such quantities and may eventually provide new insight into the long-standing tension between the inclusive and exclusive determination of these CKM matrix elements.
